Abstract

Claims (92)

1. A method comprising:

receiving a copy of a compressed audio or video file;

providing, to a remote location, the watermarking criteria or watermark embedding instructions in association with a request to obtain a copy of the compressed audio or video content.

2. The method of claim 1 , wherein the watermarking criteria comprises information associated with a perceptual model of the audio or video content.

3. The method of claim 1 , wherein the watermarking criteria comprises audio or video features that are more resilient to changes relative to other audio or video features.

4. A method comprising:

receiving a copy of a compressed audio or video file;

decompressing the compressed audio or video file to yield decompressed audio or video content;

obtaining a plural-bit identifier that is uniquely associated with a requestor of the copy of the compressed audio or video file or a device of the requestor; and

combining the watermarking criteria or watermark embedding instructions and the plural-bit identifier to yield a combined watermark signal.

5. The method of claim 4 , further comprising compressing the combined watermark signal as an object.

6. The method of claim 5 , further comprising providing the compressed, combined watermark signal object and the compressed audio or video file.

instructions to obtain a plural-bit identifier that is uniquely associated with a requestor of the copy of the compressed audio or video file or with a device of the requestor; and

instructions to combine the watermarking criteria or watermark embedding instructions and the plural-bit identifier to yield a combined watermark signal.

9. A method comprising:

obtaining a copy of a compressed audio or video file;

decompressing the compressed audio or video file to yield decompressed audio or video content;

determining a watermarking component for the decompressed audio or video content, wherein the watermarking component is steganographically hidden in the audio or video content, wherein the watermarking component includes information associated with an auxiliary watermark orientation signal or with an auxiliary watermark reference signal, and wherein the auxiliary watermark signals are separate from the audio or video file;

storing the digital watermarking component separately from the compressed audio or video file; and

providing the stored watermarking component, a unique plural-bit watermark identifier, and the compressed audio or video file to a remote location.

10. A method comprising:

obtaining a copy of a compressed audio or video file;

decompressing the compressed audio or video file to yield decompressed audio or video content;

determining a watermarking component for the decompressed audio or video content, wherein the watermarking component is steganographically hidden in the audio or video content;

storing the digital watermarking component separately from the compressed audio or video file;

combining the watermarking component and a unique plural-bit watermark identifier;

compressing the combined watermarking component and the unique plural-bit watermark identifier to form a watermark object; and

providing the watermark object and the compressed audio or video file to a remote location.

11. The method of claim 9 , wherein the watermarking component is based at least in part on a perceptual model of the decompressed audio or video content.
